Abstract: The burner for metallurgical furnaces comprises a main combustion chamber (7) and an auxiliary combustion chamber (5) presenting a plurality of outlet channels (6) communicating with the main combustion chamber (7). To the main combustion chamber there is fed in a pulsating manner a primary mix of fuel gas and air in stoichiometric ratio, and, during the intervals between the feed pulses, a secondary mix of fuel gas and air with a coefficient of excess air of 1.15 to 1.35 and at a rate of flow corresponding to 1 to 3% of the nominal rate of flow. To the auxiliary combustion chamber (5) there is instead continuously fed an auxiliary mix of fuel gas and air with a coefficient of excess air of 0.65 to 0.85 and at a rate of flow corresponding to 1 to 3% of the rate of flow of the primary mix. The combustion products of the auxiliary mix stay in the auxiliary combustion chamber (5) for a very short time, more particularly for about from 0.005 to 0.01 sec., so that they still contain, when they enter into the main combustion chamber (7), active chemical substances, and particularly hydrogen atoms and radicals containing hydrogen atoms.

Abstract: An encapsulated medium-voltage electrical load switching apparatus has four, three-position rotary switches, supported by pairs of opposing insulated half-shells, two-over-two in parallel alignment within a gas-filled sealed shut shell housing. The housing front and back have dome-shaped protrusions to maintain the seal against fluctuations in gas pressure. Bushings in the floor and ceiling of the housing, aligned with the switch face plane, provide gastight connections between the switches and external cables, enclosed fuses and transformer terminals. Switch control is provided by drives mounted on a plate at the front of the housing exterior which operate actuator arms that extend in a gastight way through the housing front and manipulate selector shafts that connect to set the switches into closed-circuited, open-circuited and grounded positions. Internal conductors establish connection from a cable through a fuse to a transformer terminal when the two upper switches and one of the lower switches are closed-circuited. The disclosed apparatus offers the advantages of low cost, compactness and freedom from maintenance.
